3 Claims. (01. 242-13)" This invention relates to new and useful improvements in armature winders and the primary object of the present invention is to an armature winderthat may be manually or power operated for effectively and eificiently winding wire about an armature. T

Another important object of the present invention is to provide an armaturewinder including 'a pair of armature gripping members having plates for receptionin a pair of diametrically opposed slots in anarmature to function as a means for guiding the insertion of wire into slots of an armature. ,7

Yet another very important object of the present invention is to provide an armature winder includin a pair of armature gripping members and embodying novel and improved, quick release means, for quickly and readily spreading the members facilitating a convenient removal of the armature from the gripping members.

A further object of the present invention is to provide an armature winder including arotatable armature holding means and a counter. actuated by the holding means for indicating-the number of revolutions of the holding means.

A still further aim of the present inventionisto provide an armature winder that is simple arid practical in construction, strong and reliable in use, small and compact in structure, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a plan view of the present armature winder; I v

Figure 2 is a side elevational view of the present armature winder and with parts broken away for the convenience of explanation;

Figure 3 is a rear-end view of Figure 2;

Figure 4 is a front end View of Figure 2; and,

Figure 5 is an enlarged fragmentary vertical sectional View taken substantially on the plane of section line 55 of Figure 1.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral It] represents a suitable base to which there is secured one end of an upright or supporting post I 2 having a notch or recess Hi in its upper end and a transverse, horizontally disposed, opening I6 intersecting the notch M. A cover plate or arcuate shield l8 embraces the upper end of the supporting post l2 and closes the notch I4.

A revolution counter 20 is supported in a substantially horizontal position by an angle bracket 22 secured to the upper end of the post l2, and the counter 20 includes an operating arm 24 that operates a counting mechanism, forming part of the counter, each time the arm 24 is reciprocated. A setting knob 26 forms part of the counter and is manually actuated to reset the counter. The counter 20 is of any suitable and well known type and is used to merely indicate the number of revolutions of an armature in a manner presently to be described.

Journaled for rotation in the opening it, is a shaft 28 having a bifurcated forward end portion 3%). The rear end of the shaft 28 supports a crank handle 32 and a driven pulley 35. A reversible electric motor 36 is mounted on the post l2 by a bracket-38and includes a drive pulley 40, on its drive shaft 42, that is connected to the driven pulley-3t by a drive belt 44. A switch 46' wiseor counter-clockwise direction.

The shaft 28 includes a laterally projecting portion 68 that is positioned in the notch It for rotation with theshaft and whichwill engage and actuate the arm 24 as the shaft rotates. A set screw 50 threaded in the post I2 is manually ad'- justable'to bear against the shaft 28 in order to prevent rotation of the shaft.

Means is provided for guiding the removal of Wire 52 from a spool of wire 54 and for retaining the wire in tension as it is removed from the spool and placed in the slots 56 of an armature 58. This means consists of a substantially L-shaped member 60 having one of its legs received in a horizontal aperture in the lower end portion of the post l2. A collar 62 is suitably held longitudinally adjusted on the member 60 and a holding sleeve or nut 64 is threaded on the member 60 to retain the member so in a selected rotated position. A pair of spring tensioned guide roller assemblies 66 and 68 are mounted on the memher and the wire 52 is trained over the assembly 68 and under the assembly 66 as shown best in Figure 4.

Means is provided for holding the armature 58 relative to the bifurcated end 30 of the shaft 28 for rotation therewith. This means comprises a pair of arcuate gripping members 10 and 72 hav- 3 ing their inner ends pivoted, as at H, to the bifurcated end 38. Set screws 16 and I8, threaded on the end 38, are adjustable to lock the members 18 and 12 in a selected spread position.

The outer ends of the members 18 and 12 support plates 88 and 82 having curved end portions 84 that constitute stops for limiting movement of the armature 58 laterally of the members 18 and 12. The plates 88 and 82 will occupy a portion of a pair of diametrically opposite slots in the armature 58 and will also function as shields and as guides for directing the wire into the armature slots.

A flexible joint is provided so that the members 18 and 12 may be quickly and readily spread in order to rotate the armature and place the plates 88 and 82 in a second pair of slots or so that the armature can be removed from the apparatus. This flexible joint is composed of first and second arms 86 and 88 having their inner ends pivoted as at 98.

The member 18 is provided with a slot 92 that slidably receives, the arm 86 and the member 12 is provided with an aperture 94 that receives the arm 88. An adjusting sleeve and abutment 96 is threaded on the arm 88 and bears against the member 12.

When the plates 88 and 82 are in use, as shown in Figure 2, the pivot 98 is disposed relatively close to the armature 58 and a shoulder 98 .on the arm 86 rests upon the member 18 adjacent the rear edge of the slot 92. By forcing the arm 86 forwardly toward the plate 88', the pivot 98 will move away from the armature and the sleeve 96 will be moved away from the member 12 causing the members 18 and 12 to spread at their outer ends. It being understood that the set screws 16 and 18 are backed up.

In practical use of the present-invention, the members 18 and 12 are spread and the armature 58 is slipped into place with the plates 88 and 82 entering a pair of diametrical slots in the armature. Next, the wire 52 is initially wrapped through the slots receiving the plates 88 and 82 and tied to itself. Then, the motor is started and runs until a predetermined number of turns has been made, whereupon the motor is stopped, the members 18 and I2 spread, and the armature rotated so that the plates 88 and 82 can be placed in another pair of diametrically opposed slots.

The quick release joint (86, 88, 98, 96) will reduce the normal time required for rotating the armature to receive the plates 88 and 8,2 to a minimum and considerably ease the handling and winding operation.

In view of the foregoing description taken in conjunction with the accompanying drawings, it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention, the same is susceptible to certain changes fully compre- 4 hended by the spirit of the invention as herein described and the scope of the appended claims.
